More People Are Focusing on Gut Health as Fermented Foods Gain Popularity
- The federal government's latest dietary guidelines specifically encourage Americans to eat more fermented food, reflecting growing interest in gut health and microbiome management.
- Followers of Health Secretary Robert F. Kennedy Jr.'s Make America Healthy Again movement have popularized fermented foods, though experts question some MAHA-endorsed fads while supporting the science behind fermentation benefits.
- Barbara Olendzki, director of the Center for Applied Nutrition at Massachusetts Chan Medical School, recommends focusing on 'whole fermented foods' like yogurt, kefir, kimchi, and sauerkraut. Consumers should seek items labeled 'live cultures' for maximum probiotic benefit.
- Not all fermented products are probiotic; beer, wine, and sourdough bread often lack live microbes after processing. Dr. Lisa Ganjhu of New York University Langone Health cautions that 'gut healthy' is not a clinical definition, advising consumers to avoid sugary items.
- Dalia Perelman, a Stanford University research dietitian, suggests aiming for two servings daily as part of a well-rounded diet with fibrous prebiotics to feed beneficial bacteria. Those with weakened immune systems should consult their doctors first.
